IMPROVEMENT IN WRINGiNG-MACHlNES.

The Schedule referred to :in these Letters Patent and part of the same.k

To all whom it may concern Be it known that I, ELBRIDGE G. W. BRTLETT,of the city and county ot' Providence, in the State of Rhode Island,have invented a new and useful Improvement in NVringing-Machines; and Ido hereby declare that the following specification, taken in connectionwith the drawing making a part of thc same, is a full, clear, and exactdescription thereof.

Figure 1 is a view in perspective of the machine.

Figure 2 is a view of the device for bringing the surfaces of therollers nearer together.

Figure 3 is a view of a clamp employed in the machine to .attach it to atub.

In the drawing- Fig. 1, A A are the standards for supporting thesqueezing-rollers B B.

The driving gear of the rollers, and the clearerrol-ler C, shown in thedrawing, are .fully described in the Letters Iatent granted to me May24, 1870, and the machine, except i-n the particulars hereinafterspecified as constituting the improvements, is the same in principle asmany machines for this purpose known to the art.

The improvements which are the subject of this patent relate- First, toa device for bringing the ,surfaccs'of the squeezing-rollers nearertogether; and

Second, to a clamp for attaching a machine to a wash-tub.

Ordinarily one or more thumb-screws are employed tocanse the boxes whichcontain the journals of the upper roller to approach nearer to the boxesof the lower roller, and thus bring the yielding surfaces of the rollerscloser together'. I n place of such screw or Iscrews I make use of thehcreinafter-describcd device.

D is a lever, whose fulcruin is at a, in a standard set in the cross-barE of the frame of the wringer. This lever has a mortise cut through itof sufiicient size to admit the squared shank of the rod F, which latteris heldin guides so that it can be readily moved for a limited distanceup or down.

The back side of the shank ofthe rod is furnished with teeth, b,constituting a rack, and with these teeth are engaged thel teeth of asegment of .a pinion, c, into which the hub of the lever D is formed.

A latch, G, is `pivoted to the lever D, as shown, the

the surfaces ot' the squeezing rollers will be brought nearer together,and bc held at such distance apart as the latch, and the catch withwhich it is engaged, shall allow.

A catch and latch-lever compress, as described, is ou several accountsmore convenient than the compressing-screw usually employed, especiallyin wringing-machines of large size, in the use of which greatinequalities in the thickness of the folds of the heavy articles 'ofclothing subjected to their action occur. A capacity on the part of themachine to be readily adapted to suoli extreme variations in thethickness of the clothing, without loss of time and without thenecessity of stopping the rollers to make the proper adjustment, ishighly advantageous.

A further improvement resides in the clamp for securing the washing andwringing-machine to a tub.

It consists in kattaching thepressure-pad or plate to the shank, whichthe thumb-screw operates, by a joint connection, so that such` clamp canbe made. to adapt itself to tubs of any size, 'and whether circular orsqnarein form.

I is a thumb-screw which Works in a collar f.

J, iig. 3, is a nut or hollow shank set in a guide in the standard. lTothis vshank the pad or pressureplate K is hinged at g. It is obviousthat by this method of construction the clampis made perfectly self-adjusting to every form and sie of tub'.

What I claim asvmy invention, and desire to secure by Letters Patent,is-

1. A catch and latch-lever compress, substantially as described, incombination with the cross-bar Hand the boxes' of the uppersqueezing-roller, as herein specified for the purposes set forth.

2. rlhe thumb-screw I, nut or hollow shank J, and lpressure-pad K, allin combination substantially as described.
